The main difference with energy storage inverters is that they are capable of two-way power conversion – from DC to AC, and vice versa. It''s this switch between currents that enables energy storage inverters to store energy, as the name implies. In a regular PV inverter system, any excess power that you do not consume is fed back to the grid.
